Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Urologic Endoscopic Procedure: Cystoscopic Examination

Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

Summary

Endoscopic ultrasonography-guided biliary drainage (EUS-BD) shows promise for treating obstructive jaundice. Procedures like EUS-guided choledochoduodenostomy and hepaticogastrostomy are feasible and safe in experienced centers, with EUS-guided gallbladder drainage also demonstrating high success.

Area of Science:

  • Gastroenterology
  • Interventional Endoscopy
  • Biliary Interventions

Background:

  • Obstructive jaundice necessitates effective biliary drainage.
  • Endoscopic ultrasonography-guided biliary drainage (EUS-BD) offers an alternative to traditional methods.
  • EUS-BD encompasses EUS-guided choledochoduodenostomy (EUS-CDS), EUS-guided hepaticogastrostomy (EUS-HGS), and EUS-guided gallbladder drainage (EUS-GBD).

Purpose of the Study:

  • To review the current status of EUS-BD.
  • To evaluate the limitations of EUS-BD techniques.

Main Methods:

  • Systematic review of English language full articles.
  • Searches conducted via MEDLINE, EMBASE, and manual literature searches.

Main Results:

  • EUS-CDS demonstrated a high success rate (93%) and EUS-HGS (97%) with no fatal adverse events in high-volume centers.
  • EUS-GBD showed a 100% success rate without serious adverse events, though based on a small number of cases.
  • Feasibility and safety of EUS-BD procedures are suggested by these findings.

Conclusions:

  • EUS-BD is a promising treatment modality for obstructive jaundice.
  • Further assessment in larger patient cohorts and comparative studies against percutaneous drainage are required.
  • Development of dedicated devices is needed to enhance the reliability of EUS-guided drainage procedures.
